El Gordo

It seems there is a recent discovery of a massive cluster of galaxies that has been nicknamed "El Gordo" which is one of the most massive cluster of galaxies known weighing in at 2 quadrillion times that of the sun. It was found using NASA's observatory and that from a Chilean telescope, which is why they named it "El Gordo" to give credit to the Chilean telescope used.

It's a very fascinating article at space.com here giving various information about "El Gordo" and is also where the picture above originated, which is a photo of the galaxy cluster.
